package update-manager 1:0.87.24 failed to install/upgrade: ErrorMessage: SystemError in cache.commit(): E:Sub-process /usr/bin/dpkg returned an error code (1)

The list of the packages that could NOT be updated (for one reason or the other), til the upgrade process was aborted, is:

- gnome-power-manager
- gnome-session (I'm using lxp-icewm)
- hal
- network-manager (which I never used anyhow)
- policykit
- policykit-gnome
- pulseaudio
- ubuntu-desktop
- update-manager

Synaptic shows NO broken packages! (though some of the above allegedly failed due to broken dependencies)

Should I try to RE-install them? (Synaptic shows them as installed and up to date!)

I mean, the system's got a few glitches right now but it's more or less usable (just very slow)

Added my current /etc/apt/sources.list

My above question about wheter I should try to reinstall the packages or not is not really appropriate for a bug report so I've asked that in the forum instead. If you can help with that, pleas go here:

I hope the rest of the informations are useful to the developers.

Thanks for your bugreport.

Please attach the files in /var/log/dist-upgrade to this bugreport.

The bugreport you mention (#176629) is most likely unreleated to the error you get, but I will verify once the logs are avaialble.

 Thanks Michael

Thanks for the answer, Michael.
